Dynamic trunks
LACP trunks are not configured in VFSM for our reference architecture. For detailed
information about the configuration steps and verification, see Chapter 5, “IBM System
Networking RackSwitch implementation” on page 155.
Important: You can see that the trunk that connects ACC-3 to AGG-2 is blocked by
the STP.
